EFFECT OF THREE KINDS OF COMMERCIAL RATION AND DEFFERENT LITTER SYSTEM ON BROILER PERFORMANCES. This study aimed to determine the effect of three kinds of commercial feed and litter of different systems on the performances of broiler chickens,three kinds of commercial rations were used, namely, A1, A2, A3. The research method using completely randomized design(CRD) with factorial pattern, treatment 3x2 with 4 replications. Treatment given that FactorA=3 Piece ration, and factor B=Cage battery andl itter. The results showed that the effect of three kinds of commercial ration and different litter system for broiler performance, either incombination or single treatment provides no significant effect on the performance of broilers. Based on the results and the study concluded that the granting of the three kinds of commercial diet and the use of different litter systems provide no significant effec ton feed intake, weight gain, and feed conversion of broilers. Different enclosure systems also provide no significant effect on feed intake, weight gain, conversion of broilers. Keywords: Rations, cage, broiler, performance

This study aimed to assess the effect of stocking density of 10, 12, 14, and 16 birds m?2 on performance, carcass and cut yields, productivity, and bone development of broiler chickens Cobb 500®. The experimental design was completely randomized design with four treatments (stocking densities) and four replications. The assessments were performed weekly at 1, 7, 14, 21, 28, 35, and 42 days. The best live weight result was found at a density of 10 birds m?2 in the period from 1 to 7 days. No effect of density was observed on feed intake and weight gain. From 1 to 14 days, the best live weights were found at densities of 10, 12, and 14 birds m?2, in addition to a higher feed intake at densities of 10 and 12 birds m?2. Weight gain was better at a density of 10 birds m?2, showing no differences from densities of 12 and 14 birds m?2. In the period from 1 to 21 days, live weight and weight gain were higher at densities of 10, 12, and 14 birds m?2. The highest feed intake was observed at a density of 10 birds m?2, which showed no difference from the density of 14 birds m?2. A difference (P < 0.05) was observed for live weight, weight gain, and feed intake of animals reared at densities of 10, 12, and 14 birds m?2 for the phases from 1 to 35 days and the total phase from 1 to 42 days of bird age when compared to 16 birds m?2, which presented lower performance. However, feed conversion of 1-7, 1-14, 1-21, 1-35, and 1-42 days and carcass and cut characteristics showed no significant differences for all treatments. On the other hand, productivity was higher in the treatments with 14 and 16 birds m?2, but without difference between each other. No interaction (P > 0.05) was observed between stocking density and age for the assessed bone parameters. Similarly, no difference (P > 0.05) was observed for bone development of broiler chickens reared at different stocking densities for the studied parameters. Thus, the increased density of 10 or 12 birds m?2 to 14 birds m?2 has no influence on zootechnical performance, carcass and cut yields, and bone development, but increases broiler chicken productivity reared in a conventional shed without air conditioning.

Foram avaliados os parâmetros zootécnicos de frangos de corte alimentados com dietas suplementadas com diferentes fontes e níveis de selênio (Se), criados sob diferentes condições de temperatura. Foram utilizados 720 pintainhos, Cobb-500, em um delineamento inteiramente ao acaso em esquema fatorial 3 x 2 x 2 (3 temperaturas ambiente: termoneutra, fria e quente; 2 níveis de suplementação de Se: nível A e B; e 2 fontes de Se: orgânica e inorgânica), com 4 repetições de 15 aves. Os níveis A e B de Se na ração inicial (1 a 21 dias) e de crescimento (22 a 42 dias) foram 0,15 e 0,30 mg/kg e 0,20 e 0,40 mg/kg, respectivamente. Selenometionina foi usada como fonte de Se orgânico e selenito de sódio, inorgânico. Os frangos criados em condições de estresse por calor apresentaram uma redução no consumo de ração e ganho de peso. Não houve influência da suplementação das diferentes fontes ou níveis de Se no ganho de peso, consumo de ração ou conversão alimentar. Os resultados são indicativos de que a suplementação de Se não melhora o desempenho de frangos de corte criados em condições de temperatura adversa. Evaluation of different sources and selenium levels for broilers at different temperatures Abstract This study evaluated the effect of selenium (Se) diet supplementation on productive parameters of broiler chickens raised under different temperatures, in a complete randomized design with 3 x 2 x 2 factorial schedule (3 environmental temperatures: cold, neutral and hot; 2 levels and two Se sources) with 4 repetitions of 15 birds. The levels of Se in rations for initial and growth phases were: 0.15 and 0.30 mg/kg; and 0.20 and 0.40 mg/kg, respectively. The organic and inorganic sources of selenium were selenomethionine and sodium selenite, respectively. There were a reducing in broiler feed intake and weight gain of the broilers housed in the hot temperature. Selenium levels or sources did not affect the weight gain, feed intake or feed conversion. It was concluded that Se supplementation did no affect the broiler performance, housed under adverse environmental temperature.

The objective of this study was to evaluate the performance of broiler chickens in different lighting programs. Broiler chickens were fed on feeders of different colours at different breeding phases. In total, 240 Cobb500™ chicks mixed at 1 d of age were used. They were distributed in a completely randomized design. The treatments followed a 2 × 4 factorial design: two lighting programs (continuous and intermittent), and four colours of feeders (white, green, blue, and red). The birds were evaluated for weekly productive performance and the data were submitted to analysis of variance and later Tukey’s test for comparison of means. In the periods 1–7, 1–21, and 1–42 d of age, lighting programs and feeder colours affected weight gain, feed intake, and feed conversion. Intermittent red feeders influenced positively the performance of birds. It is possible to replace conventional lighting programs for intermittent lighting programs. Red feeders exert a positive influence on the performance of broiler chickens.

This study aimed to evaluate the effects of feeding plans with or without addition of glycerin, in different ages, on performance, carcass yield, litter moisture and footpad lesions of broiler chickens. 540 male Cobb broilers were utilized, distributed in a completely randomized design with six treatments (treatments consisted of the inclusion or not of glycerin in diets at all periods or only at different stages: 1 to 7, 8 to 21, 22 to 33 and 34 to 42 days), in six replicates of 15 birds each. Diets were provided ad libitum. At 42 days, the average weight, weight gain, feed intake, feed conversion, carcass yield, litter moisture and footpad lesions were evaluated. There was no effect (p> 0.05) of dietary plans on the performance variables. The feeding plans did not influence (p>0,05) the carcass and cuts parameters at 42 days. However, there was significant effect (p <0.05) of the dietary plans on litter moisture and plantar lesions. Effects were observed (p>0,001) for the feeding plans, were the highest and the lowest incidence of lesions were present in the birds that consume diets with and without addition of glycerin, in the period from 1 to 42 days of age, respectively.

In this study, the effect of three different sources of maggot meals was conducted to evaluate the performance and slaughter characteristics of broiler chickens. Five diets were formulated to include Diet 1 (control) which contained 3.5 % fish meal, while Diets 2, 3 and 4 contained 3.5% maggot meal from broiler droppings (BMM),maggot meal from layers droppings (LMM) and maggot meal from rabbit faeces (RMM) respectively. Eighty (80) dayold unsexed Marshall Broilers were randomly allotted to four dietary treatments in a completely randomized design (CRD). Thedietary treatments had 20 birds each with two (2) replicates. Data were generated on proximate analysis and performance indices including feed intake and weight gain, slaughter characteristics and mortality rate. They were subjected to analysis of variance (ANOVA) and means significantly different were separated using Duncan's Multiple Range Test (DMRT) at 5% probability level. Results from proximate analysis showed that maggots from layer droppings had the highest crude protein and ether extract. Results on performance indices showed that birds fed on diet 3 (layer maggot meal) had significantly (P<0.05) best performance than others as regards feed intake. Layer maggot meal (LMM) in this study enhanced bestproductive performance compared to those from broiler and rabbit maggot.Birds fed layer maggot meal had the best (1.85) feed conversion ratio. They also had the best body weight gain (2501g) and feed intake (4627g). In conclusion, layer maggot meal is recommended as analternative animal protein source to expensive fish meal.

EFFECT OF SUBTITUTION OF BASIC RATIONS WITH PAPAYA LEAF MEAL ON BROILER PERFORMANCE.  This research aims to know the effect of substitution of basic rations with papaya leaf meal on broiler performance. Using 100 broiler chickens aged 2 weeks with an initial weight rate of 278.75 g. The design used was complete random design (CRD) consisting of 4 treatments and 5 replications. The arrangement of the treatment was as follows: R0 = 100% basal ration (RB) + 0% papaya leaf meal (PLM), R1 = 95% basal ration + 5% PLM, R2 = 90% basal ration + 10% PLM, R3 = 85% basal ration + 15% PLM. The results of the analysis of variance showed that the replacement of a portion of basal rations with papaya leaf meal had a significantly different (P < 0.05) on feed intake, daily weight gain and feed conversion. Based on the results of this study, It can be concluded that the using of papaya leaf meal can replace a portion of ration until 5% level.Keywords: Performance, papaya leaf meal, broiler chickens

This paper aimed to evaluate the metabolizability, performance and economic viability of purified glycerin inclusion in balanced diets fed to chicken broilers from 8 to 21 days old. Two experiments were conducted. In the first experiment, 100 broilers (14 days old) were distributed in a completely randomized design into two treatments, with five replications of 10 broilers. Treatments consisted of a control diet and a test diet, in which purified glycerin replaced 10% of the control diet. In the second experiment, 200 broilers (8 days old) were distributed in a completely randomized design into four treatments (0, 2, 4 and 6% of purified glycerin inclusion), with five replications of 10 broilers. The weight gain, feed intake, feed conversion, final weight, apparent metabolizable energy (AME), nitrogen-corrected apparent metabolizable energy (AMEn), metabolizability coefficients of dry matter (DMMC), crude protein (CPMC) and gross energy (GEMC), and the cost of feed per kg of broiler produced were evaluated. The AME, AMEn, DMMC, CPMC and GEMC from the purified glycerin were 3790 and 3560 kcal/kg, and 83.72, 71.52 and 86.27%, respectively. The glycerin levels did not affect (p>0.05) any of the performance characteristics (weight gain, feed intake, feed conversion and final weight). The lowest feeding cost and the highest gross margin were obtained for broilers fed with 6% purified glycerin. The inclusion of 6% purified glycerin in balanced diets for broilers from 8 to 21 days old was technically and economically feasible.

Aiming to evaluate the effect of tomato waste inclusion on productive performance and characteristics of carcass and main broiler chicken cuts, an experiment was carried out using 300 male Cobb chicks, distributed in a complete randomized design, with five rations and five replicates. Diets consisted of control ration based on corn and soybean meal and four rations with 5, 10, 15 and 20% of tomato waste. Feed intake, weight gain and feed conversion and, at the end of experiment, slaughter weight, gutted carcass without feet and head, breast, drumstick, thigh, wing, back, edible guts and belly fat were evaluated every week, as well as it was the yield. Tomato waste increased feed intake in the periods from 1 to 7, 8 to 14 and 29 to 36 days of age and worsened gain weight and feed conversion of broiler chickens up to 29 days of age. Regarding carcass weight (g) and weight of the noble parts, breast, drumstick and thighs decreased linearly in function of the use of tomato waste in poultry on pre- initial and initial phase, that is, up to 28 days old, but yield (%) was not affected except for yield of heart and liver. Use of tomato waste in ration of broiler chickens during the period from 1 to 28 days may decrease weight gain and worsen food conversion. Tomato waste may be used as ration ingredient in ration of broiler chicken in the breeding period from 29 to 42 days of age up to the level of 20% without harming weight gain and feed conversion of poultry.

Low protein intake and rapid human population growth in addition constitute a major problem facing developing countries. To solve this problem of lack of adequate intake of animal products and to increase the output by majority of Nigerians, there is the need to improve poultry and poultry products production by putting a lot of effort in the production of highly reproductive animals becomes very important. The aim of this work is to compare the performance of four breeds of broiler chickens fed a popular commercial Diet in Kuta. One hundred and twenty, day-old chicks of different breeds, and thirty each (Arbor acre, Marshal, Anak, Cobb) were selected and randomly allotted to four treatments with three replicates each in a completely randomized experimental design. Result from the experiment revealed that there was no significance (P< 0.05) difference among the treatments in terms of water intake, feed intake body weight gain and feed conversion efficiency. Anak and Cobb breeds has the highest numerical values for the most of the performance indices measured such as average weekly feed intake (1425.60g, 1272.60g), total feed intake (4714.3g, 4509.8g), average weekly water intake (4046.40ml, 4317.00ml), total water intake (12698.7ml, 14527.6ml), average weekly body weight gain (298.51g, 348.13g), and feed conversion ratio (4.87, 3.67). This research show that the Cobb breed have superior performance compare to other breeds on the same feed and under same environmental condition in Kuta. This implies that the production of the four mentioned breeds can perform in Kuta but the feed is more favourable to Cobb breed.
